ASPHALT AND LIKE DISTRIBUTOR.

. The invention pertains to a distributor for asphalt .and similar products, `and the genera-l objectof the invention is to produce a -distributor of high eticiency which is simple in construction and otherwise of a practical character.

An important object of the invention is such that when both distributors are closed the circulatory system is open, such t-hat when but one distributor is open the full 'force of the pump is applied to said distributor, and such that when both distributors are open the full force of the pump is applied between said two distributors.

Still another object of the invention isto provide a dual valve control for the distributor system, and in particular one which is operable from'a single point near the operators station.

Still other and ancillary objects and advantages of the invention will be apparent from the ensuing description of the apparatus illustrated in the drawings, in which Figurel is a rear end view of the liquid distributor truck showing the tank, the'distributing pipes and controls.

Fig. 2 is a detail view showing the pump and the intake.

Fig. 3 is a side view of the rear end as shown in Fig. l.

Fig. l is a view partly in perspective of the control mechanism'for the individual distributors and showing diagrammatically 4.5, the circulating and distributing systems.

Figs. 4a and 41 are fragmental sectional diagrammatic views showing the positionsI of the valve members when only one discharge line is open.

The device illustrated in the drawings is not to be-construed as a limitation rof the inventionbut is herein yshown only for the purpose of illustrating and describing the nature of the invention. The invention con- Still another object of the invention is.

templates all other forms and modifications of construction or other embodiments of the principles herein set forth which fall within the scope of the appended claims as limited by the prior art.

In vpractice the distributor is mounted upon a suitable support such as a frame designatedl generally by the numeral 6 at the extremen-ear end oi" which is a seat 7 for the operator and a step 8. 9 indicates the main reservoir or tank into and from which the fluid to be distributed is filled and discharged' by operation of a pump 10. The pump is arranged to be operated from a suitable 4source ofmotive power such, for exan'lple, as an internal combustion engine 11. An engine control 11" Ais provided adjacent the operators seat 7. I prefer to employ motive power independent of the motor truck so that the speed of the pump may be` controlled independently of the speed of the vehicle.

The tank 9 may be of any suitable or pre `4erred construction being preferably provided internally with heating pipes l2 and 12a, the latter communicating between end chambers 13 of the tank, suitable heaters (not shown) being provided for said pipes within a housing 15.

The pump 10 (Fig. 2) is preferably of Athe positive type and is located almost di- -rectly beneath the rear end of the tank E) (Fig. 3) being` sepa-rated therefrom .only by the casing of a valve 1G. Said valve lis ofthe three-way type and its casing communicates at its upper end with the bottom oi the tank through an aperture 17 and at its lower end with the inlet opening 18 ot' the pump 10. An intake pipe 19 communicates with one side ot' the valvecasing. 20 designates the valve member which is ar` ranged to control the flow of fluid in the operation of the pump either through the intake pipe into the pump or from the tank through the pump. The valve member is arranged to be operated by means of a hand lever 21 (Fig.` l) suitably` arranged to operate a shaft 22 which turns the valve.

The pump l0 'is arranged to be driven from the motor 1l, being connected therewith under the control of a clutch within the housing 23 arranged to be operated by a lever 24. The motor or clutch is geared to the'pump shaft by means of gearmg in4 y wardly and Ahorizontally disposed pipe 29 which I preferablv secure to the under side ofthe header by welding. The pipe 29 has interposed therein a valve 30. The valve 30 is of the three-way type so as to control the discharge of the tiuid into an inwardly extending pipe 31. Said pipe has a valve 32 interposed therein and communicates with the lower end of a U-shaped circulating pipe 33. The valve 32 lis a shut-off valve which is employed when it is desired to discharge into the circulatory system from one side only ofthe apparatus. The valve 30 is arranged so vas to control the discharge of iuid from the header into a sprayer or distributor 34 or from the header to'the circu- Y lating pipe 33 orboth. The construction at the opposite side of the apparatus is the same. The valves at the 'right hand side in Fig. l are designated bythe numerals 30a, 32 corresponding to the valves 30 and 32 at the left hand side, the nozzlebeing 34.

Valve 32a is likewise connected into the remaining end of the inverted U-plpe 33. A-

recess 35 is formedat the top of the bend in the U-pipe 33 so that the legs'of the (lll U-pipe are substantially independent pipes.

The valves 30 and 30l each communicate' with the distributors 34 and 34 respectively connected through similar pipes 36 fand swivel connections 37. A pivoted link 38 between the pipes 36 holds them parallel. Ann` operating lever 39 is provided near the operator`s seat 7 toshift the distributors laterally with respect to the truck 6, said lever acting through a connector bar 40 between the lever 39 and the link 38. f

Having thus described generally the relationship of the principal parts of the distributing system, I will now set forth the lneans by which the flow is controlled through the distributors using either one. or both as desired. Reference should be had to Fig. 4 wherein the valves controlling the How are shown with the operating mechanism therefor. From each of the valves 30 and 30 there are upwardly extending operating spindles 41 and 41l respectively which serve as operating shafts for said valves. Likewise shorter operating shafts 42 and 42a extend from the valves 32 and 32a. The operating mechanism is arranged so that any one valve of one set and the non-similar valve of the other set are simultaneously operated, and is further arranged so that each operation is performed from substantially the same point thusA permitting the operator sitting in seat 7 or standing on step 8 lto have complete control over the discharge without changing his position.

In the vicinity of the lever 39 are two.

similar hand levers 43 and 43a mounted on the spindle 41. Lever 43 is rigid with' the spindle 41, while lever 431l is loose thereon. On the spindle41a is a short rigid crank arm 44 linked by a bar 45 to the lower loose hand lever 43a. Thus the levers 43 and 43 operate the valves 30 and 30a respectively independent of. each other. Each of the shafts 41, 419,42 and 42l have rigid therewith 'crank arms 46, 47, 48 and 49 respectively. yArms 46 and 49 are in substantially a single plane Vand arms 47 and 48 are likewise in substantially a single plane. Links 50- and 51 connect the respective pairs of crank arms 46-49 and 47-48.

Other and ancillary features may be added tothe above described outfit as is desired for any particular purpose but, of course, these form no part of the present invention.

The operation of the Huid flow system is as follows: On filling the tank 9 the distributors are closed by operation of the hand levers 43 and` 43a.l In the closed position of valves 3() and 30a to the distributors, the respective circulatory valves 32 and 32a will be open so Vthat there is communication from the pump to the tank by way of the inverted U-tube 33. The valve 16 between the tank 9 and the pump 10 is. turned so that operation .of the pump draws liquid through :the intake pipe 19, and such that the opening 17 between the -valve vand the 'tank 'is closed Fig. 4. Operationofthe pump drives tlie fluid taken in through pipe 19'finto the headers 27 and 27 through the two sets of valves v30-32 and 30-32a into thetank .through the U.-tube 33. In case the li uid being used is a heavy asphalt the heating system is put in operation so .that upon filling the tank, the asphalt is heated from the pipes 12 and 12%. When lthe tank is full the valve 16 is turned to cut olf the intake pi thus to establish communicationv wit lthe tank 9 through the aperture 17. The operation o the pump may be continued, but it will now circulate the liquid from the bottom of the tank through the circulatory system to the top thus serving to heat the fluid uniformly if this is necessary.

When theliquid is to be distributed upon the road, if both distributor nozzles 34 and 34 are to be employed, the hand levers 43 and 43 of Fig. 4 are moved to the right thus opening the valves 30 and 30a leading to the distributors and cutting olf communication to the circulatory system. Upon shutting off supply to the distributors the valves 32 llo and 32 will be openand the valves 30 and 30a will establish communication from the pipes 29 to the circulatory system, thus permitting liquid to flow unimpeded by the action oit shutting olf supply to the nozzles and thus saving the pump from undue strain.

If it is desired to use but one of the ldistributing nozzles say, nozzle 34, the hand lever 43 only is moved to the right to establish communication to said nozzle. The mechanism described is so arranged that upon opening the valve 30 to communicate with the nozzle 34, it cuts oft' communication to the circulatory system through the valve 30 Fig. 4, By virtue ofthe connecting bar 50 the valve 32a on the other side in the circulatory system is also shut off Fig. 4b thus permitting full force of the pump 10 to be applied directly to the distributing nozzle 34. In the absence of the connecting bar 50 in this instance the valve 32a would be open and valve 30a would be in such a position that the liquid from header 27a could How through the two valves 30a'and 32 back into the tank thus putting only a part of the pump pressure upon the open distributor nozzle 34. Of course, it will be understood that the operation of the distributing nozzle 34a singly is effected in the same manner by the manipulation of the hand lever 43a. Be-

sides these advantages, the arrangement described permits the operator to maintain a single location on the wagon and to operate the various parts of the distributing system without change of his position.
